What is JSON?

JSON is both easy for humans and machines.

By James Nunns

JavaScript Object Notation, or JSON, is a minimal, readable format for structuring data.

JSON is primarily used to move data between a server and web application and operates as an alternative to XML.

Basically, it provides a human-readable collection of data that can be accessed in a logical manner.

JSON is based on a subset of the JavaScript Programming Language and is a text format that is completely independent, however, it uses conventions that are similar to programmers that use the C-family of languages such as C++.

Did you know JSON is built on two structures? Find out what they are on the next page.

Built on two structures, a collection of name/value pairs, and an ordered list of values, these are universal, meaning that the majority of modern programming languages support them in one form or another.

The basic data types for JSON are: number, which is a signed decimal number that may contain a fractional part and may use exponential E notation, but it cannot include non-numbers like NaN.

String is a sequence of zero or more Unicode characters, Boolean deals with values of either true or false.
